He aha ke kumu o ka adhesion o ka tape PTFE?

ʻO ka tape PTFE i hana ʻia e Jiangsu Aokai New Materials, kahi mea hana ʻoihana o ka tape PTFE, hoʻohana i ka silicone pressure-sensitive adhesive (silicone PSA) . ʻO ka hoʻopili ʻana o ka silicone PSA e hahai ana i nā ʻanuʻu honua ʻekolu o PSA: wetting - adsorption - cohesion , akā ʻokoʻa kona ʻano.

1. Ka pulu a me ke kino adsorption

ʻO ka silicone PSA o ka tape PTFE kahi hui o:

·  Kelepona silikoni  (hāʻawi i ka maʻalahi a me ka palupalu)

·  MQ silicone resin  (hāʻawi i ka rigidity a me ke kāʻei)

Ma lalo o ke kaomi māmā, kahe wikiwiki nā kaulahao silikoni maʻalahi e pulu i ka ʻili ʻili o ka substrate. Loaʻa ka adsorption kino ma o nā ikaika van der Waals a me  hapa nā paʻa hydrogen .

2. 'Sea island' hale: kaawale o ka pili a me ka pili

ʻO kēia ka mīkini ʻokoʻa loa o ka silicone PSA i ka tape PTFE:

·  MQ resin (ka 'mokupuni') : paʻa paʻa ʻekolu ʻano hīnaʻi e like me nā hale i hoʻopuehu ʻia i ka papa pipili. Hāʻawi lākou i ka hoʻopili  - ʻo nā hui silanol (Si–OH) ma ka resin MQ e hana i nā pilina ikaika me nā ʻili e like me ke aniani, metala, a me ka ʻili silikoni.

·  Kelepona silikoni (ʻo ka 'kai') : ka māhele polymer mau e hāʻawi i ka ikaika hui  e pale aku i ka hemahema o loko i ka wā peeling.Ma ka hoʻoponopono ʻana i ka lakio o ka resin MQ i ka lāʻau silicone, ka ʻili  a me ka ikaika o ka ʻili . hiki ke hoʻohālikelike pono ʻia

3. Hoʻonui ʻia ka hui ʻana o ka hui crosslinked

I ka wā o ka mālama ʻana a i ʻole ka hana ʻana, ua hoʻopili ʻia nā kaulahao kaila silicone me ka hoʻohana ʻana i nā peroxides  a i ʻole nā ​​​​catalysts platinum  e hana i kahi pūnaewele ʻekolu. ʻO kēia ka mea e hōʻoia i ka hoʻomaʻemaʻe ʻana o ka ʻili i waena o ka ʻaoʻao  ma mua o ka pau ʻole ʻana  (ka haki ʻana i loko o ka adhesive) ma lalo o ke kaumaha.

Hōʻuluʻulu manaʻo

ʻO ka hoʻopili ʻana o ka tape PTFE e like me kēia:

·  Hoʻomaʻemaʻe ʻia ka ʻili o ka ʻili a hāʻawi i ka adsorption kino ma o nā ikaika van der Waals.

·  MQ resin ('island') hāʻawi i ka pili; hāʻawi ka huila silicone ('sea') i ka pilina.

·  Hoʻoikaika ʻia ka hoʻohui ʻana i ka hoʻohui ʻana a pale i ka hāʻule ʻole o loko.

Hāʻawi ʻia ka ʻike ma luna e Jiangsu Aokai New Material Technology Co., Ltd.

No nā kikoʻī hou aku e pili ana i nā palena, nā noi a me nā hoʻoponopono maʻamau o kā mākou laina huahana piha me ka PTFE uhi ʻia i ka fiberglass fabric, PTFE kiʻekiʻe wela tape, PTFE kiʻekiʻe wela mesh kāʻei, laminating machine seamless kāʻei, hoʻokahi ʻaoʻao PTFE lole, kiʻekiʻe wela kūpaʻa conveyor kāʻei a me ke kiʻekiʻe wela pale fiberglass lole, e ʻoluʻolu e kelepona mai iā mākou:

·  Laina Hana Hana: Mr. Guo 18944819998

·  Mr. Liu 13705266308

Ke kākoʻo nei mākou i kahi loiloi lawelawe ʻoihana a me ka ʻoiaʻiʻo a ke kūpaʻa nei mākou e hāʻawi iā ʻoe i nā hoʻonā hoʻokahi  a me ka lawelawe hoʻolohe!
